Be it known that I, CHARLES citizen of the United States, residing at Pomeroy, in the county ofMeigs and State of Ohio, have invented certain new and useful Improvements in Trolley-Poles; and I 'do hereby declare the following to be a 1111,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. r

This invention relates to new and useful improvements in trolley poles fortrain 1oco-' motives and the principal object of the 1nvention is to provide a device which. will eliminate the necessity of using' more than one trolley pole. v

A further object of the invention is to provide a novel mounting for the trolley pole which will securely hold the same. against accidental movement and yet allow for the free shifting movementof the same laterally ofthecar. V

. erence will be had to the accompanying Withthe foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter morefully described, illustrated in the accompanying drawings and claimed.

In describing the invention'in detail ref drawings wherein like characters designate like and correspondnig parts throughout the several views, and in which- Figure 1 1s a s de elevation of a mme locomotive showing said trolley. pole at tached thereto,

Fig. 2 is a fragmentary end elevation of i the car showing the. trolley pole mounted thereon,

Fig. 3 is a detail perspective view'of the guiide on which the trolley pole is mounted, an r Fig. 4 is a detail perspective view of the slidin carriage carrying the trolley pole;

' Re erring to the drawing, the numeral 1 designates an ordinary electric locomotive used for mining purposes which runs on the usual track 2 and the numeral 3 designates,

the ordinary trolley wire for furnishing power for the driving of the locomotive.

The trolley pole is designatedby the numeral 4: and is provided at its upper end with a sleeve 5 formed with a pair of upwardly extending ears 6 between which the trolley wheel 7 is rotatably mounted. The

The carriage above referred to is desigflanges 12 and riveted or otherwise attached as at 13 near the upper side of the plate lower en diof the poled en'largedas at it natedby the numeral lO- and comprises a. plate 11 formed atits side edges with guide 11 is a U-shaped yoke 14 which'is apertured as at 15 to receive the bolt9, in order to pivotally' connect the trolley pole to the car- .riage. It will be understood that any suitable spring structure 16 may be attached to the yoke in such a manner as to hold the trolley pole upagainst the wires.

The yoke above referred to is slidableton' I a the guide, designated generally by the nu meral 17, which comprises a plate 18 formed 'at its side edges with reduced flanges 19 whichflanges are spaced upwardly as illus trated infFigsfl and 3 so as to accommodate the lower portion of the guide flanges 12 which are bent around the flanges 19 and thus slidably mounts the carriage on the guide. Attached to the plate '18 and extending upwardly therefrom near the opposite ends are stop pins 20 which limit the lateral movement of the carriage on the guide as will be clearly seen upon'reference tothe drawin It w ll be un derstood'that' the carriage may be'attached to the top of the car as illustrated in Fig. 1.

c It will be apparent from the foregoing that thetrolley may be shifted to the propel. po-

' sition to receive the .wire and when the car in use when the caris traveling along and the trolley wire is to one side of the track, 1 a

enters another part of the mine where the trolley wireis on the opposite side of the I track th'e trolley pole may beshifted to the .OPPOSltG side of the car, thus avoiding the necessity of using more than one trolley pole.,-

' From the foregoing description taken in connection with the accompanying drawings the advantages of construction and of the r method of operation of the improved trolley pole will be readily apparent to thosef skilled in the art to which this invention appertains and, while in the foregoing descrip-f tion the principle of theoperation of this in vention has been described together. a with understood that certain minor features of various features of construction, it is to be Y ment of parts may be altered to suit practical conditions provided suchalter-ations' are comprehended Within the'scope of hat claimed.

What is claimed is V v A'trolley pole comprising a supporting plate secured to a locomotive and having the opposite edges of one facefcut away to define horizontally extending flanges andforming spaces between themselves and the locomotive, a sliding plate resting on said supp0rt- I ing plate and extending transversely thereof and having its ends bent to-engage theedges or said first named flanges, sa1d second15' named flan es having their ends bent horizontally to underlie the first named flanges, a yoke secured to said sliding plate, and a pole pivoted to the yoke. v V In testimony whereof I aflFix my signature 20 V presence of twowitnessesJ AR E ESSEX c Witnesses: I Q i EJJi-Trrus v J. .R.
